EVGA expands the SuperNOVA G2 PSU series

As users are becoming more and more aware of how PSUs operate and what the real energy requirements of their systems are, sales of high wattage units decrease in relevance to middle range units. Many manufacturers realize that and they began marketing high performance products of reasonable power output and pricing instead of focusing their efforts on high output units. In that light, EVGA expanded their very popular G2 PSU series downwards, adding 550W and 650W models to it.
EVGA's G2 series is synonymous with the excellent balance between cost, quality and performance. We have seen their capabilities in our review of the 850W version. After all, there is good reason why the Super Flower Leadex platform is so popular. The new 550W and 650W models are physically smaller but share the same features, so it is very likely that they are based on a Super Flower platform as well.
According to EVGA, the main features of the new 550 G2 and 650 G2 PSUs are:
- 80 PLUS Gold certified, with 90% (115VAC) / 92% (220VAC~240VAC) efficiency or higher under typical loads
- Highest quality Japanese brand capacitors ensure long-term reliability
- Fully Modular to reduce clutter and improve airflow
- NVIDIA SLI & AMD Crossfire Ready
- Heavy-duty protections, including OVP (Over Voltage Protection), UVP (Under Voltage Protection), OCP (Over Current Protection), OPP (Over Power Protection), and SCP (Short Circuit Protection)
- Ultra Quiet Fan with ECO Intelligent Thermal Control Fan system (Zero Fan Noise < 45°C)
- Unbeatable 7 Year Warranty and unparalleled EVGA Customer Support.
We should note that both units are rated at 50°C and have a ridiculous number of connectors for their power output. Even the 550W version has three PCI Express connectors (two 8 pin and one 6 pin) and nine SATA connectors. Apparently, EVGA is very confident about the capabilities of their new units - or of their OCP, at least. Nevertheless, the 550W version should be able to easily power any system with a single CPU and a single GPU, with the possible exception that the extreme combination of an AMD FX-9590 and an R9 295X2.
The new G2 series units are available as of the 12th of June.

Awesome... and love the all black braided cables. Yup..this 650 could very well be the power source for my new Z97 build.Lolimaster - Saturday, June 13, 2015 - link
It would be nice if they also focus on the 300-500w range.Without overclock and even some undervolt tweaks you can have a 4790K + GTX980 consuming less than 300w. Also factor in mid range gaming rigs or APU builds. I would love to see Platinum/Titanium rated PSU below 500w.

But why would you want to undervolt a 4790 and a 980 combo anyways? they already use low enough wattage. It is a enthusiast build as it is. If you wanted to do anything just get a low wattage i7/i5 and a 970/980.I just feel if you have a 4790 I do not know why you would want to undervolt/clock it.
I am still sporting a 4.5-4.9ghz Coolermaster 140xl cooled 2600k that is at least 4.5 years old. Its like the energizer bunny and just keep on performing right up there with the 3770k and 4770k and 4790k's especially in gaming situations around the max difference in performance is around 10% on certain titles but with my 2600k's OC it kind of negates that even with 2 evga 770 4gb classified cards on 8x pcie 2.0 displayed on a LG 34um95 3440-1440 IPS monitor. Still powered by my original Corsair tx850 PSU. I always want more power then I need since running a psu at 60-75% usage instead of 80-90% really exstends the life of the pSU " knock on wood" but I have never had a PSU fail. Overkill is way better then underkill in my book. Kinda like carrying a gun, I would rather have it and not need it then need it and not have it.

A lot of people want to save money on PSUs. Lower wattage PSUs are cheaper and if you need to choose between a high quality 300W PSU and a low quality 500W PSU the choice isn't necessarily obvious. Simply looking at efficiency curves, one sees that most PSUs are most efficient at half the rated output, so an 850W PSU should ideally be used with a 425W load though it will handle more at a disproportionately high heat load.Then you have other people who assume that a 300W PSU uses 300W, an 850W PSU uses 850W. I'd hope that there's nobody like that here, as any of the PSU reviews clearly indicate the load from the wall as a function of the output load. However a 300W PSU would handle a 100W load with a higher efficiency than an 850W PSU would. This means the 850W PSU does consume more energy for such a load, so a 300W PSU might save money on both the PSU itself and the electric bill. However, the 300W PSU is going to have a lower performance cooling parts so the 850W PSU probably runs cooler despite having to deal with a bit more heat.

You can get massive saving in energy consumption just losing maybe 5-10% total performance. Or no performance loss just with undervolt and nothing else. CPU/GPUs come with voltages well over their actual needs with even more voltage the moment they need to use their turbo modes.You should try and see for yourself. Low is never low enough with default settings.

As far as I know, it's not recommended to run the PSU close to maximum load for extended periods of time. Also, please bear in mind that a PSU is the most efficient at around 50% load.The 550W would be perfect for you. :)

No, it's fine to run the PSU at close to maximum power. It's just that the PSU will not be running at its peak efficiency in that scenario. Peak efficiency is typically around 50~70% load, depending on how the PSU is designed.Also, power output will degrade over time, if there are components, like electrolytic caps, in the PSU. How fast depends on the quality of parts used in the PSU and how hot those parts are running.

Excellent. Most PCs even upper midrange gaming rigs rarely need more than 600W so having more choices for 450-650W PSUs is always good.meacupla - Saturday, June 13, 2015 - link
It looks like they might have skimped on acoustics or fan. I mean, that stamped fan grill says "I don't care about airflow restriction or noise".
